Underground Mine Refuge Chamber Expectations

mining, the following year on August 6, 2007, an incident occurred at the Crandall Canyon Mine in Utah. Six miners and three rescue personnel died. One new technology to emerge amid efforts to reduce fatalities is the underground refuge chamber (see Fig. 1). Refuge chambers are movable chambers that are either made of

Stresses Due To Underground Mining Using A Finite Element

Particular features of the finite element procedure presented here and used for mining sequence simulations, are summarized as follows: (1) Different types of pre-mining stress states can be treated. (2) A mining sequence with options in relief force applications can be simulated. (3) Closure of previously mined openings is indicated. (4) Modelling of rock joints and faults is possible. (5 ...

Underground mining is divided into three broad classes: caving, stoping and other methods. Caving is referred to the controlled fragmentation of rocks due to the flow gravity, whereas the term stoping is the excavation of a stable opening of small or large di mensions. Underground mining …

An Approach To Realizing Process Control For Underground

Jun 10, 2015 The excavation and production in underground mines are complicated processes which consist of many different operations. The process of underground mining is considerably constrained by the geometry and geology of the mine. The various mining operations are normally performed in series at each working face. The delay of a single operation will lead to a domino effect, thus delay the …
